MT1-B-34-620-1-A24-B-C

The MT1-B-34-620-1-A24-B-C is a single-pole circuit breaker manufactured by Littelfuse Inc., designed for overcurrent protection in electrical systems. It operates at a rated voltage of 250V and supports a continuous current rating of 20A. The device utilizes a magnetic hydraulic delay trip mechanism, which provides instantaneous response to high fault currents while maintaining stability against temporary inrush currents typical in industrial and commercial loads.

Mechanically, this component employs a push-pull actuator for manual tripping and resetting. It is engineered for panel mount installation, allowing secure integration into control panels, distribution boards, and equipment enclosures. The unit does not include illumination features, focusing on reliable mechanical operation and clear status indication through the actuator position.

The breaker carries multiple international approval certifications, including UL1077, CSA, and CCC standards, ensuring compliance with safety requirements across North America, Europe, and China. Its robust construction makes it suitable for protecting circuits in machinery, power distribution units, and automated control systems where precise overcurrent management is required.
